dt-bindings: serial: sh-sci: Convert to json-schema
Convert the Renesas Serial Communication Interface ((H)SCI(F)(A|B)) Device Tree binding documentation to json-schema. Split the bindings in 5 files, one per major type, to ease expressing constraints. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Rob Herring <robh@kernel.org>

|
||||
|
||||
When compatible with the generic version, nodes must list the
|
||||
SoC-specific version corresponding to the platform first, followed by the
|
||||
family-specific and/or generic versions.
|
||||
|
||||
- reg: Base address and length of the I/O registers used by the UART.
|
||||
- interrupts: Must contain one or more interrupt-specifiers for the SCIx.
|
||||
If a single interrupt is expressed, then all events are
|
||||
multiplexed into this single interrupt.
|
||||
|
||||
If multiple interrupts are provided by the hardware, the order
|
||||
in which the interrupts are listed must match order below. Note
|
||||
that some HW interrupt events may be muxed together resulting
|
||||
in duplicate entries.
|
||||
The interrupt order is as follows:
|
||||
1. Error (ERI)
|
||||
2. Receive buffer full (RXI)
|
||||
3. Transmit buffer empty (TXI)
|
||||
4. Break (BRI)
|
||||
5. Data Ready (DRI)
|
||||
6. Transmit End (TEI)
|
||||
|
||||
- clocks: Must contain a phandle and clock-specifier pair for each entry
|
||||
in clock-names.
|
||||
- clock-names: Must contain "fck" for the SCIx UART functional clock.
|
||||
Apart from the divided functional clock, there may be other possible
|
||||
sources for the sampling clock, depending on SCIx variant.
|
||||
On (H)SCI(F) and some SCIFA, an additional clock may be specified:
|
||||
- "hsck" for the optional external clock input (on HSCIF),
|
||||
- "sck" for the optional external clock input (on other variants).
|
||||
On UARTs equipped with a Baud Rate Generator for External Clock (BRG)
|
||||
(some SCIF and HSCIF), additional clocks may be specified:
|
||||
- "brg_int" for the optional internal clock source for the frequency
|
||||
divider (typically the (AXI or SHwy) bus clock),
|
||||
- "scif_clk" for the optional external clock source for the frequency
|
||||
divider (SCIF_CLK).
|
||||
|
||||
Note: Each enabled SCIx UART may have an optional "serialN" alias in the
|
||||
"aliases" node.
|
||||
|
||||
Optional properties:
|
||||
- dmas: Must contain a list of two references to DMA specifiers, one for
|
||||
transmission, and one for reception.
|
||||
- dma-names: Must contain a list of two DMA names, "tx" and "rx".
|
||||
- {cts,dsr,dcd,rng,rts,dtr}-gpios: Specify GPIOs for modem lines, cfr. the
|
||||
generic serial DT bindings in serial.yaml.
|
||||
- uart-has-rtscts: Indicates dedicated lines for RTS/CTS hardware flow
|
||||
control, cfr. the generic serial DT bindings in serial.yaml.
|
||||
|
||||
Example:
|
||||
aliases {
|
||||
serial0 = &scifa0;
|
||||
};
|
||||
|
||||
scifa0: serial@e6c40000 {

|
